#     Merge tag 'perf-tools-fixes-for-v5.9-2020-09-03' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull more perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Use uintptr_t when casting numbers to pointers
#     
#      - Keep output expected by 3rd parties: Turn off summary for interval
#        mode by default.
#     
#      - BPF is in kernel space, make sure do_validate_kcore_modules() knows
#        about that.
#     
#      - Explicitly call out event modifiers in the documentation.
#     
#      - Fix jevents() allocation of space for regular expressions.
#     
#      - Address libtraceevent build warnings on 32-bit arches.
#     
#      - Fix checking of functions returns using ERR_PTR() in 'perf bench'.
